Tliis invention relates to the method of producing patterns. or designsby stencillng over irregular surfaces and more particularly to themethod of producing a stripe design 011 the spokes of automobile Wheels:

Heretofore the striping of. automobile Wheels has been by hand andstencils have been'found' inipracticaldue to the irregular tofsecure'aresilient stencil under pressure withits edges in contact with anirregular surface so that the design maybe sprayed thru the stencil. '1

Theinvention will be more clearly under 2 stood by reference to thefollowing description taken in connection with the accompany ingdrawings in which:

Fig. Tie a sectional View thru an automobile-wheel and asupport thereforshow i mg a method of securing the stencil thereon. Fig. 2 is a planview ofthe stencil. Fig. 3is a sectionalview on line 3+3 of Filr. 4 is a.fragnientairyplan iew of a portion of the stencilillustra ting themovement of the edges around the opening. Fig. 5is a sectional View online 5-5 of Fig. 4.

Referring particularly to Fig, 1 of the drawings, a pedestal 1 0liasbeen shown havingawork supporting member 12 pivoted atits upperflend. Extending'thru theWork supporting member 12 is a reciprocal lockingmember 14: and. upon Which I have shown a tapered sleeve 16. adapted toreceive the hub 18 of. anjautomobile WlIGBlQD. Atone end of the member14:Il1 ave provideda piston 22 which fits angair chamber 24 in thesupport 1 12. Pipes 26 communicate With the chainberQl: at oppositesidesof the piston 22 so thatby positioningavalve, not shown, one is adaptedto supply an'air pressure and the other receives the exhausted air atthe opposits side of the piston. The'pistonmay be 60 moved in eitherdirection by causing an air pressure be applied thru either pipe theother acting as theexhaust conduit.

The Wheel hub,18.is placed on the tapered sleeve 16 andthe stencilplacedover the outer surfaceof the Wheel andcohnected to TO F E themember 14 in such a manner that its The end ofthe member 14: oppositethe piston 22 is provided With a groove 28 adapted to receiveapivotedhook 30 on the stencil. By applyingpressure at one side of thepiston 22; the stencil may be moved away from the Wheel and by applyinga pressure at the opposite side of the piston the stencil is resilientlyheld in contact with the'irregular Wheel surface.

The stencil comprises a hub p0rtion32 and a plate portion 34. The hubportion is adapted to fitover the member 14: and the hook 30.is pivotedon its outer and; A plu rality ofv springfingers 36and 38 are. securedto the hub member. The springs '36 are se cured to the plate portion34:by projections 40 received in slots 42 in the springs 36. .A

head portion 4:4: holds the plate 343011 the springs 36. The slipconnection has been provided to permit the saline tension on eachportion ofthe plate. a

. The figure to be stenciledor the spoke stripes are cut in the plate34: providing openings ldthru'vvhich the design is sprayed. In.

forming a stencilrfor the particular design illustrated, V shapedportions 48 are formed andthe springs 38 engage these resilientlymovement to the left holds the stencil tightly againstthevvheel andholds the latter onthe tapered sleeve 16:

forcing them against the irregular surface of the spokes. The V shapedportions are bent slightly belovv the normal contacting surface so that\vhen they engage and. disengage the Wheel surface a wiping effect isobtained. The portions 50 between each of V the openings 46 are providedWithdepressed portions 52uaround the edge of the openings so that theyslightly slideyvhen' making contact. It is this feature that makesstenciling irregular surfaces possible because the edges ofthestencilare slightly-drawn away from the Y paint before it p is removed from thework thus preventing blurring or running of the paint.

In order that the stencil may be as flexible as possible the plate 34 ismade as a small as possible and in order to cover the entire wheel asegmental flange is secured to the outer ieriphery of the plate. Thisflange is made up of a plurality of flanged members 54 shown rivetedtothe plate 34 as at 56.

The stencil is positioned on the wheel angularly by a pair of resilientclips 58 which engage one of the spokes.

It will be understood that various changes may be made in theconstruction and arrangement of parts without departing from the spiritof my invention, that the stencil may be used for applying variousdesigns to parts other than automobile wheels, and that it is not myintention to limit its scope other than by the terms of the appendedclaims.

hat I claim is:

1. The method of striping spoked wheels which consists in applying aresilient stencil to the surface thereof, forcing the stencil againstsaid surface to cause the edges of the openings in said stencil to slideon said s rface, and spraying paint thru said openin 2. The method offorming designs on 11'- regular surfaces which consists in applying aresilient stencil to said surface, pressing the stencil against saidsurface to cause the edges of the openings in said stencil to slide onsaid surface, and applying paint to said surface thru the openings insaid stencil.

3. The method of stripping wheels which consists in applying a resilientstencil to the surface thereof, pressing the stencil against saidsurface at points on portions between the openings of said stencilwhereby the edges of the opening slide on the wheel, and applying paintto said surface thru the openings in said stencil.

4. A stencil of the class described comprising a central hub member, aplate spaced from said hub member and provided with openingscorresponding in shape to the design desired, resilient flanges at theed as of the openings, and spring members secured to said hub adapted tofrictionally engage portions of said plate, certain of said springmembers adapted to connect said plate to said hub.

5. A stencil of the class described comprising a supporting member, aplate spaced fro n said supporting member and provided with openings,spring members secured to said supporting member adapted to engage theportions of said plate between said openings and adapted to form aconnection bet-ween said plate and said support, and depressed portionsin said plate around the openings in said plate.

6. A stencil of the class described comprising a supporting member, aplate resiliently connected to said supporting member and provided withopenings thru which paint may be applied, and resilient depressedportions on said plate around the edge of said openings.

7. The method of striping spoke'd wheels which consists in applying aresilient stencil to the surface thereof, forcing the stencil againstsaid surface to cause the edges of the openings in said stencil to slideon said surface, and spraying paint thru said openings, then sliding thestencil on the surface away from the opening.

8. The method of forming designs on irregular surfaccs which consists inapplying a resilient stencil to said surface, pressing the stencilagainst said surface to cause the edges of the openings in said stencilto slide on said surface, and applying paint to said surface thru theopenings in said stencil, then sliding the stencil on the surface awayfrom the opening.

9. The method of applying a stencil marking to a surface which comprisesplacing a flexible stencil on the surface, pressing the flexible stencilto thereby cause the edges of the openings to slide toward the portionof the surface to be painten, and removing the pressure after paintingto permit the edges to slide awayfrom the painted surface prior toremoving the stencil from the work.

10. The method of applying a stencil marking to a surface whichcomprises sliding the edges of the openings in the stencil to ward thesurfaces to be marked, applying a coloring through the openings, andsliding the edges of the openings away from the mark surface prior toremoving the stencil from the work.

11. A stencil comprising a body portion having openings through whichpaint may be applied, the edges around the openings being movable in aplane parallel to the plane of said body portion.

12. A stencil comprising a body portion having openin through whichpaint may be applied, the edges around the openings being normally outof the plane of said body portion and yieldable to be moved underpressure into the plane of said body portion.

13. A stencil comprising a body portion having openings through whichpaint may be applied, resilient means normally forcing the edges aroundthe openings out of the plane of said body portion and yielding topermit the edges to be moved into the plane of said body portion whenthe stencil is applied to the work.
